The "gene shears" technology is a synthetic one of these molecules that is being developed for the treatment of viruses. One of these molecules regulates cellular production of glucosamine-6-phosphate. Hepatitis D relies on one of these molecules for its replication and viability, and another is used by plant viruses to process the products of rolling circle replication. The latter is a hairpin one of these molecules, a form which, like the hammerhead variety of these, does not require a metal ion to be catalytically active. These molecules are able to catalyze aminotransferase activity, but they are most notable for their ability to cleave themselves and are thought to be evolutionarily related to the spliceosome.
